For example it could have been solved by giving new version of fdisk like fdisk1 or something.

fdisk is meant to manage raw MSDOS partitions and related types, and has never done anything else. If you think it would be so easy to nail new and unrelated functionality onto the side, you're welcome to, but if you make even the most minor error, people will crucify you for ruining their data. Writing a partition editor isn't something to be done in an offhand manner.

Microsoft mostly still uses this boot schema too, making it very hard to avoid, and the better alternatives aren't universally supported.

Now they have included gdisk and parted which is kind of redundant .

Not really. gdisk is GNOME I believe, while parted runs anywhere, doesn't even need a GUI. That's crucial if you want to edit partitions in rescue-cd conditions, or do any kind of automatic partition editing.

Anyway, you're mistaking the forest for the trees again. It's not the partition editor which overcomes the limitations -- the partition editor doesn't get stored in the boot sector, after all. It's the partition types themselves. MSDOS partitions have these limitations. Some more modern partition editors can write GPT partition tables, which overcome these limits.

partitio

PARTITION(8)						      System Manager's Manual						      PARTITION(8)

NAME

       partition - make a partition table

SYNOPSIS

       partition [-mf] device [type:]size[+*] ...

DESCRIPTION

       Partition  makes  a partition table on device using the types and sizes given.  It may be used in combination with repartition(8) for auto-
       matic installation of Minix.

       You may give up to four type:size[+*] specifications for the partitions.  You may also specify holes before, between, and after the  parti-
       tions.  A hole differs from a partition specification by not having a type.

       The first hole is by default 1 sector to make space for the primary bootstrap and the partition table.  The other holes are 0.

       The  type  field is the type of the partitition in hexadecimal.	The size field is the partition's size in sectors.  The + or * may option-
       ally be added to indicate that the partition must be expanded to contain any leftover space on the device or to mark the partition active.

       Partitions are padded out to cylinder boundaries, except for the first one, it starts on track 1.  Some operating systems care about  this.
       Minix and MS-DOS do not.

OPTIONS

       -m     Minix only, no need to pad partitions.  This is the default for subpartition tables.

       -f     Force making a partition table even if the device is too small.

EXAMPLE

       partition /dev/hd0 01:16384 81:40000 81:2880* 06:20000+

       Partitions  disk 0 into an 8 Mb DOS partition, 20 Mb Minix /usr, 1.44 Mb Minix / (active), and a DOS partition of at least 10 Mb at the end
       of the disk.  (06:0+ would have been ok too, it's just a sanity check.)

SEE ALSO

       hd(4), part(8), repartition(8).
